IEC/IEEE 60079-30-2:2015

Explosive atmospheres - Part 30-2: Electrical resistance trace heating - Application guide for design, installation and maintenance

IEC/IEEE 60079-30-2:2015 provides guidance for the application of electrical resistance trace heating systems in areas where explosive atmospheres may be present, with the exclusion of those classified as requiring EPL Ga/Da (traditional relationship to Zone 0 and Zone 20 respectively). This standard also provides guidance for explosive atmospheres incorporating the Division method of area classification that may be applied by some users of this standard. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. It does not cover devices that operate by induction heating, skin effect heating or direct pipeline heating, nor those intended for stress relieving. This first edition of IEC/IEEE 60079-30-2 cancels and replaces the first edition of IEC 60079-30-2 published in 2007 and constitutes a technical revision. This edition includes the following significant changes, apart from a general review and updating of the first edition of IEC 60079-30-2, harmonization with IEEE Std.515, with respect to the previous edition:
- the relocation of trace heater product design methodology and requirements to IEC/IEEE 60079-30-1;
- the relocation and/or duplication of information on installation, maintenance, and repair to the MTs under SC31J for their addition into IEC 60079-14, IEC 60079-17, and IEC 60079-19;
- the inclusion of more detailed information on safety showers and eyewash units;
- the introduction of Annexes from IEEE Std. 515. Please refer to the Foreword of the document for the significance of changes between IEC 60079-30-2, Edition 1.0 (2007) and IEC/IEEE 60079-30-2, Edition 1.0 (2014). Keywords: electrical resistance trace heating systems, Division method of area classification

Atmosphères explosives - Partie 30-2: Traçage par résistance électrique - Guide d'application pour la conception, l'installation et la maintenance.

IEC/IEEE 60079-30-2:2015 fournit des lignes directrices pour l'application des systèmes de traçage par résistance électrique dans les emplacements où des atmosphères explosives peuvent être présentes, à l’exception de ceux classés comme exigeant l'EPL Ga/Da (relation traditionnelle à la Zone 0 et la Zone 20, respectivement). La présente norme donne également des lignes directrices relatives aux atmosphères explosives intégrant la méthode de classement des emplacements par division qui peut être appliquée par certains utilisateurs de la présente norme. Elle fournit des recommandations pour la conception, l'installation, la maintenance et la réparation des systèmes de traçage, y compris le matériel associé de commande et de surveillance. Elle ne couvre pas les dispositifs qui fonctionnent par chauffage par induction, chauffage à effet de peau ou chauffage par impédance, ni ceux destinés au relâchement des contraintes. Cette première édition de l'IEC/IEEE 60079-30-2 annule et remplace la première édition de l'IEC 60079-30-2 parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes, hormis la révision générale et la mise à jour de la première édition de l'IEC 60079-30-2 et de l'harmonisation avec la norme IEEE 515, par rapport à l'édition précédente:
- déplacement de la méthode de conception des résistances de traçage et des exigences dans l'IEC/IEEE 60079-30-1;
- déplacement et/ou reproduction des informations relatives à l'installation, la maintenance et la réparation à l’intention des équipes de maintenance (MT) relevant du SC31J, dans l'IEC 60079-14, l'IEC 60079-17 et l'IEC 60079-19;
- introduction d'informations plus détaillées relatives aux douches de sécurité et aux bassins oculaires;
- introduction des Annexes issues de la norme IEEE 515.
